Abstract: A multiple antenna system comprises at least two dipole-type radiators with first and second radiator elements, respectively, which are arranged at a distance from a reflector arrangement. A phase shifter arrangement with a phase shifter adjustment device is connected to the first and second radiator elements to adjust the phase relationships between the first radiator elements and between the second radiator elements. A decoupling arrangement is coupled to a decoupling adjustment device. The decoupling adjustment device is mechanically coupled to the phase shifter adjustment device, so that when the phase shifter adjustment device is moved, the decoupling arrangement: is changeable in its length, width and/or shape; or is changeable in its position, whereby the change of position is accelerated or only partially synchronized with the adjusting movement of the phase-shifting device; or is changeable in its position, wherein the decoupling arrangement is arranged within at least one of the radiators.
